Abstract
The utility model discloses a rolled plate commutator copper sheath, belonging to the field of commutator manufacturing technology. The rolled plate commutator copper sheath is technically characterized by comprising a copper sheath body, a plurality of internal hooks are formed inside the upper end part of the copper sheath body and are uniformly distributed along the inner edge of the upper end part of the copper sheath body, wherein the length of the internal hooks is from 30 to 35mm. The rolled plate commutator copper sheath has simple structure and the pulling-out force of copper sheet up to over 25KG, and is suitable for manufacturing micro-motor commutator.
Description
Technical field
The utility model relates to a kind of commutator copper sheathing, more particularly, relates in particular to a kind of rolled plate commutator copper sheathing that electrical micro-machine uses.
Background technology
The micromachine manufacture process of commutator, mainly comprise operations such as base, cold extrusion, pressure injection resin, crotch, groove milling, in the above-mentioned course of processing, because the backwardness of mould, make in the course of processing a lot of operations need the workman manually to finish or many moulds of certain operation needs could be realized, make that the low and quality of production efficiency is difficult to guarantee, add and lack the research that concerns between each modular construction of commutator and overall performance, make the overall quality of commutator fail to increase always.In the base process, curved interior hook in need on base substrate, molding, when being used for the pressure injection resin with the resin moulding, to improve adhesion each other; Traditional interior hook length is generally about 28mm, hook makes the whole pulling-out force of commutator between 12~15KG in this, along with improving constantly of motor speed, the commutator of this quality can not adapt to the development of micromachine, when motor speed reaches 30,000 rev/mins, will shorten the useful life of this commutator a lot, and have potential safety hazard.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, the rolled plate commutator copper sheathing of pulling-out force more than 25KG.
The technical solution of the utility model is achieved in that a kind of rolled plate commutator copper sheathing, comprise the copper sheathing body, form hook in many groups in copper sheathing body upper end, hook is uniform along copper sheathing body upper end inner edge in many groups, and the length L of wherein said interior hook is 30~35mm.
Above-mentioned rolled plate commutator copper sheathing, the length L of wherein said interior hook is good with 32mm.
After the utility model adopts said structure, rise to present 32mm by length from 28mm with hook in, hook and resin-bonded get more firm in making, pulling-out force is increased to more than the present 25KG from 12 original~15KG, and remain on about 30KG, increased the whole serviceability of commutator greatly.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
Consult Fig. 1, shown in Figure 2, a kind of rolled plate commutator copper sheathing of the present utility model, comprise copper sheathing body 1, in copper sheathing body 1 upper end, form hook 2 in 12 groups, hook 2 evenly distributes along copper sheathing body 1 upper end inner edge in 12 groups, interior hook 2 length L in the present embodiment are 30~35mm, and are good with 32mm.Adopt commutator of the present utility model, the pulling-out force of copper sheet all more than 25KG, remains on about 30KG, compares 12~15KG in the past, has improved the overall quality of product greatly.
